One price. No tiers.

180€ /day
Average day rate · 20% VAT on top

A day rate that covers everything: dev, reviews, project management, deployment. Less than an equivalent Paris agency. Not a bait price.

What they say.

“We had two quotes over €60k. Delivered in 5 weeks for a quarter of the price. Clean code, I had it audited.”

CEO · Kenta
“The estimator is stunning — the final quote was within 8%. Three weeks saved on the quote ping-pong.”

“The 7pm daily updates are addictive. You know exactly where your project stands without ever chasing.”

07 / FAQ

The questions that come up.

Why is your rate that low for a French agency?
+

Lean structure, no Parisian office or army of salespeople. Savings go straight into the price. We remain a French company, French contract, French VAT.

Is the AI estimator really reliable?
+

Trained on our scoping sessions and 120+ delivered projects. Average deviation from the final quote: under 10%. For atypical briefs, we re-validate at scoping.

Which projects do you refuse?
+

Nothing under 3 person-days (not worth it for you). No speculative crypto. No clones of existing products. Anything else, we'll talk.

Who owns the code at delivery?
+

You do. 100%. Source code, deployment accounts, credentials, domains — all transferred. No lock-in clause.

How does day-to-day tracking work?
+

Dedicated client portal, automatic update every evening at 7pm: progress, deliverables, screenshots, questions, invoices. Weekly video call to validate milestones.

What happens after delivery?
+

30-day warranty on bugs within the delivered scope, then 90 days of free support on minor iterations. Beyond that, flat-rate or time-and-materials maintenance contract.
